When possible, BFGMiner automatically configures itself for solo mining.The #allblocks keyword makes it submit all blocks locally, no matter what pool it was found for.This helps the block propagate faster and prevents the pool from performing the selfish mining attack.

Having an odd issue since I upgraded to 5.1.0, but some times BFGminer only sees one GPU/card. No other application has this problem, even other OpenCL tools (e.g. video coders) or games in CrossfireX. I can't even seem to manage to forcibly get it to see the other.

System is on a 990FX chipset, two R9 280X cards, on Windows 8.1 Pro, with scrypt GPU mining and GPU auto-detect at the command line. No, this issue doesn't happen in Ubuntu, but this machine has other duties via Windows that need the CPU overnight, which is also when I mine.

While I was installing a larger water cooling system, I also took the GPU cards out to dust, and when I re-installed them, I managed to swap their positions (accidently). For what ever reason, BFGminer picks them both up immediately, AND I am getting better performance in all OpenCL tools now. I'm qualifying this to hardware being picky.
